UNITED STATES PATENT OFFICE JoHN BLAIR, on NEW YORK, N. Y.

FOUNTAIN-PEN.

EPECIPICATION forming part of Letters Patent No. 386,448, dated July 24, 1888.

Serial No. 260,807. (No model.)

To all whom it may concern:

Be it known that I, JoHN BLAIR, of New York city, New York, have invented a new and Improved FountainPen, of which the following is a specification.

This invention relates to a fountain pen which is so constructed that some of the ink fed to the pen by a bottom feed is stored above the pen after having passed through the pen-slit. Thus the pen is always ready for use and a general objection to l'ountain-pensviz., that they will not write properlyis overcome.

The invention consists in the various features of improvements more fully pointed out in the claims.

In the accompanying drawings, Figure 1 is a top view of my improved fountainpen. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a bottom view of the same, and Fig. 4 a detail face view of collar i.

The letter (t represents the usual hollow handle,constituting the ink-reservoir and adapted for the reception at its open end of the nozzle I). This nozzle is centrally bored,and has a shoulder or offset, 0, as shown.

(I is the pen proper, which is received by the enlarged forward bore of nozzle 1) and abuts against otfset 0. Above the pen there isa strip of rubber or other material,e, which also abuts against offset a and extends to a short distance within the tip of pen (I. It will be seen that this strip, which I term the ink-retainer, does not communicate directly with the reservoir a. Moreover, as the strip is no permanent attachment to the pen, it may be readily removed if the pen is to be cleaned.

Below the pen d there is the feed-tongue f,

made of suitable material and entering with one end the reservoir a, while its other end reaches to the proper point beneath the pentip. This tongue is held against the pen by a curved flexible key, 9, that bears with its ends against tonguef and with its body against the inner bore of nozzle I). In this way all the parts are properly held in position.

The ink that is fed to the underside of pen d by means of tonguef escapes in part through the slit of the pen and settles upon the upper surface of the same. Here it is collected beneath the ink-retainer c, and thus sufiicient ink will always remain above the pen to start it, even if the feed-tongue should not work properly after the pen has not been used for some time.

h is the ordinary cap for protecting the pen when not in use. To prevent this cap from rolling and from-falling out of the pocket, I surround it by a square or angular collar, 72, made of rubber or other material.

I claim as my inventiou- 1. The combination of ink-retainer c with nozzle Z),and with the fecdbarf and key 9, sub stantially as specified.

2. The combination of hollow handle a, nozzle I), and ink-retainer c with the fcedtongne f and curved key substantially as specified.

3. The combination of fountain-pen a, having cap h, with the angular collar 2', substantially as specified.
